Crossflow
(1600) Engine Replacement Part Numbers
Note: Part numbers should fit engines with a 711M block
(1971 to 1981). Most parts will also fit earlier blocks
and very early engines with the chambered head but check
first! |
| This is a reference for all those hard to
find replacement part numbers. Mostly they relate to the
standard items but sometimes a "performance"
part has also been listed if it is a common replacement.
If you have any additions or corrections please email
Tim Hurst at timhurst@beer.com
and let him know. |
